The Force Sensor 0.5" 14.7mm – Circular is a thin, flexible Force Sensitive Resistor (FSR) designed to detect and measure changes in applied force, pressure, and touch intensity. The sensor features a circular active sensing area of approximately 14.7mm diameter and works as a variable resistor whose resistance decreases as the applied force increases.
The sensor uses Polymer Thick Film (PTF) technology and has a simple two-terminal resistive interface. When no force is applied, the resistance is very high. As pressure is applied to the circular sensing area, the resistance decreases, allowing the relative force level to be measured using a simple voltage-divider circuit connected to a microcontroller's analog input.
With a useful force sensitivity range of approximately 0.2N to 20N, the sensor is suitable for touch controls, robotic grippers, pressure-sensitive buttons, wearable electronics, electronic musical instruments, occupancy detection, and human-machine interfaces. The thin and lightweight construction makes it easy to integrate into compact devices and surfaces where conventional mechanical force sensors may be too large.
The sensor can be used with Arduino, ESP32, STM32, Raspberry Pi with an external ADC, PIC, AVR, RP2040, and other controllers capable of reading analog voltage signals.
